Debugger: Use queued connection for menu actions

Browse Source 
Pass the parent calling object to the addAction() functions and use a
queued connection. This prevents the following sequence of events:

1. The menu is dismissed when selecting a menu item.
2. The deletion gets queued via deleteLater().
2. The onTriggered action gets invoked and opens a dialog box.
3. The dialog box triggers the events to be processed.
4. The menu is deleted when processing the events, while still in the
   event function to handle the dismissal.

This only affected the watch menu since the others were leaked. Added
cleanup handlers for the other debugger menus to avoid leaking them.
